Zo all whom it may concern. I

State of Massacgiusetts, have invented oer-l tain new and use ul Im rovements in Hook- Setting Machines, of w ich the following 1s a. specification.

This invention relates to machines for setting lacing hooks, and particularly to those winch are used for operating upon shoe uppers; There are two types of machines for:

the setting operations.

this purpose, namely, t ose which insert the: hooks one at a time. and those which insert a plurality of hooks atone time.

This invention relates to the type in -Wl110l1 g thev hooks are inserted one at a time and in? which the work is fed step by step between One of the important features of the in 'vention is the means for feeding the work step by step. The feeding means is adapted to feed the work in one direction or in the; o posite direction at the will of the operator. g n advantage of this type'of feeding means is that the usual special age for positioning the work at the .outset o a setting operation I c j of the anvil. The hoo -posit1on1ng member may be omitted and the hooks may be 'correctl-y located in the work by causing .the-

teedingmeans to feed the work from right to left'when operating upon one side of an upper and from left to right when operating it moves from the top toward the bottom of serted the upper. lit is a comparatively simple matter to locate the top hook in an upper,

but it is comparatively difficult to locate the hooks in one side of the upper in the same relative position as those in the .other side 'of the up er when one series of hooks is in- 8y beginning at the top and "the other series is inserted by beginning atthe bottom and feeding toward the-top. Any convenient part of the machine may serve in the present instance as a gage for locating the top edge of theupper when placing the work in operative position, thus dispensing with a. special gage for that purpose.

Another important feature of the invention is the combination of hook inserting mechanism and hook. feeding mechanism which makes the usual work plate unnecessary. The work is fed, in the present ease,

-: same position the work is released'by the feeding jaws it pair of coiiperative jaws which are closed and opened so as togrip and release the wprk and which are reciprocated laterally to 'efiect the step by step feeding movement. The jaws are 0 erated so as to return to. the

er each feeding step. When is held in position by a yielding pnesser-foot which cooperates with .the hook-sup orting member. The work is thus held at a 1 times by some part of the operating mechanism so that it cannot become dislodged. The omission-of the usual work plate or table facilitates the positioning and feeding of the work because it leaves a clear unobstructed space for the hands of the-operator. The advantage of this feature is especially important in operating upon what 1s known as blind hookwork.

The hook-supporting member is rovided with a hook-positioning member w ich has separate confronting port-ions adapted to embrace a hook between them while the hook is on the supporting member, fort'he purpose of maintainin the hook in the line is adapted to be withdrawn from operative position to free the work pre aratory to each feeding movement. In t is embodiment of the invention the hook-supporting member has amovement toward and from the anvil, but itis fixed as to lateral movement. The hook-positioning member is so mounted as to move toward and from the anvil with the hook-supporting member,.and it is provided with mechanism for retracting it laterally at the appropriate time with relation to the feeding operation. The construct-ion and operation of the hook-positioning member aresuch that the work may be fed in either direction when the hook-positioning member is retracted.

In conjunction with the reversible feeding mechanism, the machine is provided with a driving clutch and startin mechanism whereby the operator may rst select the direction of feedin movement and then set the driving clutch y a single movement of the starting. treadle.

The invention comprises various other improvements, all of which are illustrated upon the accompanying drawings and described in the following specification.

Referring to the drawings: Figure 1 rep- -resents a right side elevation of the machine for adjusting the ranjge of movement and the 7 pressure of the anv as indicated by line 44 in Fig. 1.

The same reference characters indicate the same parts wherever they occur.

The several mechanisms are mounted in a frame 35 which is provided with bearings 36 for a main power shaft 37. The hook-settingmechanism comprises cotiperative members which are carried respectively by plungers 38 and 39. These plungers are mounted in suitable bearings at the front of the frame 35 and are adapted to move vertically toward and from each other. The upper plunger carries an anvil, indicated at 40, and the lower plunger carries a hook-supporting member indicated at 41.

The construction of the hook-supporting member is best shown by Figs. 9, 12, 14 and 22. The member 41 is afiixed in a recess in the upper end of the plunger 39, and it comprises a lip or plate which is adapted to occupy the throat of a book, as shown by Fig. 22. The hooks are conducted from a suitable reservoir 42, hereinafter described, by a main raceway 43 from which they are transferred one by one by a suitable feeding device to an auxiliary hookrace 44. The lower end of the race 44 is located in a plane below the plane of the work, and the hooks are transferred from it to the supporting member 41 when the latter is at 1ts lowest position. The operation of the anvil and hook-supportin member 41 is as follows: When the mac ine is at rest, the anvil 40 and the hook-supporting member 41' are both raised to their highest positions, as shown by Fig. 1. When the machine is set in motion, both members 40 and 41 descend, the member 40 descending to operative position and the member 41 descending to receive a hook from the race 44. The member 40 is first to arrive at operative position, and the member 41 thereafter moves upwardly, thereby inserting the shank of'the hook through the work and clenching it 'lowing mechanism, which is illustrated by Figs. 1, 2 and 20: The upper end of the plunger is provided with ahead 45, which is provided with a transverse groove for the reception of a sliding block 46. The block 46 is carried by a wrist pin 47 affixed to a rock shaft 48. The. rock shaft 48, mounted in suitable bearings on the frame 35, receives its motion from a rock shaft 49 which is arranged in alinement with it and to which it is connected by an adjustable connection whereby the shaft 48, may be adjusted to shift the range of movement of the plunger. The rear end of the shaft 49 is provided with a wrist pin 50. The wrist pin is oscillated by a connecting rod 51 whose lower end is formed'with a slot 52 through which the main shaft 37 extends. Cams 53 and 53 aflixed upon the shaft cooperate respectively with cam rolls 54 and 54 mounted upon the connecting rod 51 and furnish the movement for operating the anvil. The adjustable connection between the shaft-s 48 and 49 is shown in detail by Fig. 4. The forward end of the shaft 49 is provided with alever 55, and the shaft 48 is provided with a lever 56. The lever 55 is provided with a threaded block 57 which is connected to it by a swivel connection, and the lever 56 is provided with a similar block 57 which is likewise threaded and swiveled. The threads in the two blocks are re spectively right-hand and left-hand, to cooperate with corresponding threads upon a turnbuckle 58 by which they are connected. When the turnbuckle is rotated it turns the lever 56 in one direction or the other with relation to the lever 55 and thereby shifts the, range of movement of the anvil to a corresponding degree. The turnbuckle is provided with a check nut 59 which is provided with a suitable handle by which it may be turned to force it against one of the blocks. As shown by Fig. 1, the rear end of the shaft 48 abuts against the forward end of the shaft'49 within the hub of the lever 55, the hub constituting a bearing for the shaft 48.

The mechanism for operating the lower plunger 39 is shown by Figs. 1 and 17. The plunger is provided with cam rolls 60 and 60 which are engaged respectively by cams 61 and 61" aflixed upon the shaft 37 The device for transferring the hooks one by one from the race 44 to the hook-supporting member 41 is shown by Figs. 1, 8 and-21. The lower end of the race 44 is in alinement with a plunger 62 which is fitted to slide in a bracket 63 attached to the frame 35. The slide is reciprocated by a lever 65 pivoted at 64 .to the frame 35. The lever is moved forward by a cam 66 on the shaft 37 and is movd backward by a spring 67. The cam engages a roll 68 mounted .on the lever. For the purpose of avoiding breakage of the parts in case a hook becomes stuck in the raceway 44, the connection between the lever 65 and the plunger 61'is made yielding. For this'purpose the plum ger is bored to receive a connecting rod 69 and a compression sprin 70. The rod 69 is formed with a longitu inal.slot 71 which is occupied by a transverse pin 72 in the plunger. Although the. forward movement of the lever 65 is positive, the forward movement of the plunger is yielding, and in-- asmuch as the backward movement of the lever 65 is-eifected by the spring 67 the back ward movement of the plunger is likewise yielding.

The device for feeding the hooks one by one from the main raceway 43 to the raceway 44 is shown by Figs. 1, 8 and 21. The feeding device, which is of well known construction, is in the form of a lever, indicated at 73. The lever is provided with a lip 74 which moves-to and from alinement with the lower end of the raceway 43 in a well known manner. The feeding device is mounted upon a fulcrum stud 75 and is turned in one direction by a spring 76 and vin the other direction by a lever which rehook becomes stuck in the feeding device or in either of the raceways. The operating lever for the feeding device 73 is indicated at 77. This lever consists of a strip of flexible sheet metal affixed to a holder 78 mounted upon a fulcrum pin 79 projecting from the-frame 35. The free end of the flexible strip 77 is bent backward as shown by the drawings so that it may embrace a wrist pin 80 carried by the feeding device. The free end of the holder 78 is beveled as indicated at 81 for cotiperation with a roll 82 mounted at the upper end of the lever 65. When the lever 65 is moved forward by its cam, the feeding device 73 is raised by the spring 76 and also by the weight of the lever 77. When the lip 74 of the fdeding device is at its highest position, as

shown by Fig. 21, it is adapted to receive 8. This movement of the feeding device retracts the lip 74 from the hook and permits the hook to descend to the lower end of the placed to permitthe transfer of the hook when the plunger 62 is thrust forward. The bracket 63 is \provided with an adjustable stop .screw .84 which is adapted to be en-- aged by a portion of theifeeding device 73 or the'purpose of positioning the Ii 74' in the desired posit-ion to receive a hoe from the raceway 43.

' The feedingjaws for feeding the work step by step are illustrated by Figs. 1, 8,10, 11, 15 and 16. The feeding jaws are in' the form of. levers according to this embodiment of the invention and are indicated respectively at 85 and 86. Thefree ends of stud 106 which pro ects through a hole in the feed jaws are preferabl provided with swivel work-engaging mem 'ers 85 and 86- (Fig. 11) which enable the work .to be turned or guided as desired. The lever 85 is formed with a sleeve 87 and is loosely mounted upon a vertical pin 88. The lever 86 (see Fig. 16) is afiixed in any suitable way to the pin 88. The pin is mounted to oscillate in suitable bearings in the frame 35. The lever 86 is oscillated by a plunger 89, and for this purpose it is provided wlth a slotted arm 86 which is engaged by a block 86 swiveled. uponthe slide 89. The

slide is mounted in a guide on the frame and is engaged by a friction device 89 which prevents backlash. (See Fig. 16.) The slide is pivotally connected to the upper end of an operating lever 90. The lower end of the lever 90 is provided with a. cam

roll 91 which coo erateswith a-cam, hereinafter described, y which it may be oscillated to impart feeding movement of the. jaws 85, 86, either from right to left or from left to right. The fulcrum for the lever 90 is herein shown inadjustable form whereby it may be shifted to increase or decrease the length of feeding movement imparted 'to the feed jaws. As shown by'Fig. 1, the

lever 90 is provided with a longitudinal slot 92. This slot is occupied by a sliding block 93. A bracket 94 afiixed tothe'frame 35 is rovided with a slot similar to the slot 92. ut which does not appear in Fig. 1 because it is coextensive with the slot 92 and is con- 'cealed by the lever 90. A sliding block 95 similar to the block 93 is arranged in the aforesaid slot in the bracket 94. A pin 96 extends through both blocks 93 and 95 and projects'in bothdirections beyond the lever 90 and bracket 94. (See Fig. 24.) The ends of the pin 96 bear in blocks 97, 97 which are engaged by the forked ends of 'a split lever 98. The lever is mounted upon a lcrum stud 99. andis provided with a handle 100 by which it may be oscillated to shift mam the pin 9 which is the fulcrum for the lever 90.

Referrin 100 is provided wit a a sliding pin 101 which is adapted to cooperate with a notched. sector 102- which is clamped upon the stud 99 and 1s:adapted to beadjusted about the hi hi s. 3 and 26, the handle stud. A finger lever. 103 carried by the handle 100 is connected to the pin 101 and is subjectto the force of a spring 104 by which the pin is normally held in engage- .ment with the sector 102. ,The sector is preferably provided with a series of index marks as shown by Fig. 3, and the handle 100 is provided with an index member 105 I ada ted'to cotiperate with the index marks to indicate the desired adjustment of the handle.

';The feed jaw 86 has near its free end a I the jaw as shown by Figs. 1, 10 and 11. This stud transmitsfeeding movement from .the jaw 86 to the jaw 85. The jaw 86 has no movement other than'oscillatory movement about the axisof its pin 88, but the jaw 85 is moved toward and from the jaw 86 to ef-' feet the necessary opening and closing of the jaws to releaseand grip the work. The jaws are normally closed b a spring 107 (see Fig. 1) which is coiled a out the sleeve 87 Y and which is compressed between the jaw and a convenient portion of the frame 35; The

jaw 85 isopened against-the force of-the spring by a suitable cam and connections. (See Fig. 15). For this purpose the jaw 85 is provided with-an arm- 108 which is arranged-to be engaged by a roll 109 carried by'one arm of a bell crank 110. The bell crank is mounted upon a fulcrum pin 111 projecting fromthe frame 35 and is connected by a link 112 with the upper end of an operating lever 113. The'lever is mounted u 'on a fulcrum pin .114 projecting from the rame 35 andis provided with a roll 115 which coiiperates with a cam 116 aflixed to the shaft 37 The connections between the cam and the feed jaw operatedv positively by the cam to open the jaw and are o'ie'rated in v the opposite direction to close th jaw by a spring 117 one end of which. is a.tached to the link 112 and the other end of which is attached to a fixture 118. The area of the arm 108 is such that some portion thereof will always be in coiiperative relation with the roll 109 notwithstanding oscillatory movement of the arm.

The feeding jaws are operated sothat they may move in either direction from a median position. The jaws are closed in every instance when they' are in sald med1an position, and the feeding movement begins when thejaws are in the median position so that the work will be fed from right to left if the jaws are moved from their median pos'ition to the left, or will be fed to the right if the jaws are removed from their medlan position to theright. The jaws release the work after each step and return to their me-' dian position to take a fresh hold upon the work.

Feeding movement for the jaws is produced by a cam which is fixed upon the shaft 37 and which engages the roll 91 on the feed lever 90. This cam is illustrated by Figs. 1, 5, 6, 7 and 28. As shown by Figs. 1, 6, and 28, the cam has a median groove 120 and two branch grooves indicated at 121 and 122. A

switch 123 carried by the cam disk is adapted to guide the cam roll 91 into the branch 121 or lnto the branch 122, as the case may be, depending upon its position. As shown by solid lines in Fig. 6, the switch member is in position to deflect the cam roll into the branch 121, while the dotted lines in said figure indicate the otherposition. of the switch which would deflect the cam roll into the branch 122. The switch member may remain in either position indefinitely so as to cause step bystep feeding movement exclusively in one direction or the other, or it may be shifted from time to time regardless of the number of step by step feeding movements for the purpose of reversing the direction of feeding-movement.

The desired osition of the switch member may be selecte at will and is determined by the positions of two controlling pins indicated in Figs.- 1 and 28 at 124 and 125.

The pins 124 and 125 are mounted in suit-' able bearings in the frame'35, one on either side of the cam. The pins are movable. longitudinally in their bearings, and their upper ends are adapted to coiiperate with the ends of a sliding member 126 mounted in the cam disk so as to be movable endwise,

therein in parallelism to the axis of the cam. The ends of the sliding member 126 are beveled, as-shown by Fig. 28, and they project slightly beyond the end faces of the cam disk. Referring to Fig. 7, a tooth 127 is formed upon the slide midway between its ends. This toothcoeperates with an oscillatory stud 128 in the same relation as a rack and pinion, the tooth 127 constituting the rack, and the stud 128. being provided with a single notch to receive the tooth and constituting the pinion. The switch member 123 is preferably formed upon the stud 128, although it may be formed as a separate member and' rigidly attached to the'stud, if desired. A spring follower 128 coacts with either of two fiat faces on the stud to hold the switch member in either of its extreme positions. .So long as the pin 125 is depressed, the switch member will remain in the position shown by Fig. 7 and by sol d lines in Fig. 6, regardless of the number of revolutions of the cam. When it is desired to shift theswitch member, the pin 125 is raised so that itwill intercept the ath of rotation of the right-hand end of t'e slide 126 and the ,pin 124 is depressed so that it will be out of the path of-rotation ofthelefthand end of the slide. The right-hand end v: of the slide will therefore strike against the pin 125 when the cam is driven, and the slide will be shifted to theleft as the result of the c'otiperation of the beveled end with the pin- :125. "This movement of the slide will be transmitted through the tooth 127 and stud 128 to the switch member, and the switch member will be shifted to the. left. The

switch member may thereafter remain in its left-hand position through an indefinite number of revolutions of the cam until the pin 124 is raised and pin 125 depressed. The shlftmg of the pins 124 and 125 in this way controls the position of the switch member,

but the motive power by which the switch member is shifted is furnished in'each in by a lever 132, and the stud on the "pin 125 is engaged by a lever 133. The two levers -are mounted upon a fulcrum stud 134, and

they are provided with rods indicated respectively at 132 and 133, These rods may extend to treadles (not shown). The controlling mechanism for the switch is adapted to be operated in conjunction with a starting clutch for the shaft 37 so :that the operator, by depressing a single treadle, may

first place the pins 124, 125, in position toeffect the desiredshifting of the switch and may set the starting clutch to drive the shaft 37. Any suitable starting clutch may be employed for thispurpose, the clutch illustrated being a well known form. The startingcln'tch is contained in the hub of a pulley 135 mounted upon the shaft. The clutch mechanism contained in the pulley is shown by Figs. 1 and 29. The pulley is loosely mounted upon the shaft and is presumably driven continuously in one direction by a belt (not shown). The hub of the pulley is bored out for the reception of a collar 136 ailixed to the shaft, and is rovided with one or more clutch teeth 137 which are adapted to engage a clutch pin 138 mounted in the collar. The pin 138 is adapted to slide to'and from the path of the teeth 137, and it is controlled by a starting rod 139. The starting rod is mounted to slide in suitrble bearings in the frame 35 ward and from the shaft 37. Ahead 140 on the outerend of the pin 138 is formed with a beveled face 141 which is adapted to Fig. 29,'so that the force of the spring 143 will be transmitted to the starting pin to normally project the same into operative relation with the clutch. teeth 137.. The

\ function of the starting rod 139 is to hold the clutch pin 138 out of driving'position,

as shown by Fig. 29. The starting rod is normall held in coiiperative relation with the hea 140 by a spring 144 which is compressed between a ortion of the frame 35 and a collar 145 a xed to the starting rod. When the starting rod is depressed a ainst the tension of the spring 144 it may res tracted from engagement with the head 140,v

whereupon the starting pin 138 will be projected into driving relation by its spring 143. In this way driving connection is formed between the continuously driven pulley and the shaft. The shaft will continue to rotate so long as the starting rod 139 held de ressed, but when the starting rod is release it will be restored by its s ring 144 to the position shown. The hea 140,

revolving with the clutch, will engage the upper end of the startin rod and will be.

retracted by the action 0 the inclined face 141 so as to disengag1 from the drivingtoot 137.

The levers 132 and 133 bywhich the cam switch 123 is shifted are connected to the starting rod 139 so that they may be used ,to effect the setting of the clutch in addition to the function first explained. For this purpose the fulcrum 134 for thelevers 132 and 133 is mounted upon the collar 145 aflixed to the starting rod. When one of the treadle rods 132 or 133*is depressed, the

sins 124 and 125 may or may not be shifted, epending upon their position; but in any event the starting rod 139 will be depressed to effect thesettmg of the clutch. If the operator selects the treadle rod which will e ect a shifting of the pins 124 and 125,

' the shifting movement of the ins will take place before the starting ro 139 is depressed, because there is no appreciable resistance afforded by the'pins and they will respond more readily than the s'tartin rod 139 which is subject to the force 0 the spring 144. From the foregoing description of the cam switch mechanism it is obvious that the switch is not shifted immediately when the pins 124, 125, are shifted, but that the.

switch will remain in its prior position until the cam has been rotated so far as to move the slide 126 into engagement with one of the pins. I

- jaws.

the clutch pin 138 When the work is released by the feed jaws it is clamped upon the hook-supporting member 41 by a yielding Presser-foot 146. The presser-foot and-hook-supporting member remain in cotiperative clamping relation throughout the period when the feed jaws are opened and are returnin to their median osition, and the presseroot is not retracte from the hook-su porting member until after the feed jaws ave closed upon the work. The resser-foot is, of course, retracted prior to the beginnin of feeding movement, but it is moved bac into clamping relation at the end of each feeding movement and prior to the opening of the The work is therefore held at all times either by the feeding jaws or by the presser-foot and hook-supporting member.

The resser-foot is illustrated by Figs. 1, 3, 8 and 9, and is adjustably attached to a transverse member 147 at the lower end of a lunger 148. The plunger is fitted to sli e in a suitable guide in the frame 35 and is provided with a stud 149 which is engage by a bell crank 150. Thebell crank is mounted upon a fulcrum stud 15 1 projecting from the frame 35 and is connected by a link 152 with an operating lever 153- (see Fig. 19) mounted upon a fulcrum stud 154 projecting from the frame 35.

The lever 153 has a cam roll 155 which 00- operates with a cam 156 on the shaft 37. A

spring 157 connected to the link 152 and to a suitable fixture on the'frame' normally holds the resser-foot against the hook-supporting member and keeps the cam roll 155 against its cam.

'A work guide or gage 158 is shown by 7 Figs. 1, 8, 10 and 16. The work-engaging ortion of the guide extends horizontally tweenthe feed jaws, and it is provided with two arms; 158. which extend toward the rear of the machine and which are fixed by setscrews in-suitable bosses on the frame.

The (hook-supporting member 41 is provided with a hook-positioning member 160,

illustratedby Figs. 1, 8, 9, 10, 12,21, 22 and 23. The function of the hook-positioning member is to engage the hook on the hook-supporting member and keep it in alinement with the anvil. For this purpose the hook-positioning member is provided with two fingers 161 which are separated sufiiciently to admit the head of a hook between them. The confronting faces of the fingers are adapted to enga e the 'sides of the hook and prevent latera movement of the hook. The hook-supporting member is provided with a retaining device 160 for the purpose of preventing dislodgment of the hook toward the rear. The retaining device, which is of well known construction is pivotally mounted in the member 41 and is adapted to engage the head of a hook as shown by Fig. 8. The device is normally 1 42into the upper end of the raceway 43.-

held in engagement with a book by a compression spring. The member 160 isadapted to slide upon, the horizontal" surface 162 at the up er end of the plunger 39 and is held upon t e surface 162-by the under face 163 of the hook-supporting member. The forward end of the member 160 is pivotally connected to a pin 161 which has telescopic engagement with a lever 165. The lever is mounted upon a fulcrum pin 166 and its lower end is provided with a cam roll 167' which 'cotiperates with a cam 168' on the shaft 37. (See Fig. 25).- A spring 169 connected to the lever 165 normally holds the member 160 in operative position and keeps the roll 167 against the cam 168. The cam is so timed ms to retract the member 160 upon the completion of a setting opera.- tion and prior to the feeding movement of the jaws 85 and 86. The retraction of the member 160 carries the fingers 161 out of the path of feeding movement of the hook which has just been clenched in the work,

and it is immaterial whether the work be fed to the left or to the'right.

' The cams for raising the nresser-foot and for opening the feed jaws are both timed to permit the presser-foot and feed jaws to remain in clamping relation'upon the work when the machine is at rest. Any appropriate means may be provided for raising the presser-foot and for opening the feed jaws against the tension of their respective springs, for the pur ipse of inserting and removing the work. ig. 31 illustrates a device for accomplishing this purpose. The device comprises a bell crank 170 from which two pins 171 and 172 project laterally. The bell crank is adapted to be attached to the frame 35 in such position as to' place the two pins behind the levers 113 and 153 respectively, as shown. A rod 173 may be used to connect the bell crank with a suitable treadle (not shown). crank is arranged in the relation shown, the levers 113 and 153 may both be moved when the treadle rod is depressed, with the result of raising the presser foot and o ening the feed jaws. The arrangement 0 the pins 171, 172, does not interferewith the movements imparted to the respective levers by their respective cams. The bell crank may be normally held retracted against a stop pin 174 by means of a spring 175.

The drawings illustrate mechanism for feeding the lacing books from the reservoir This mechanism is shown by Figs. 1, 3 and 30. A rotatable feeding disk 176 of well known construction is arranged in the reservoir and is afiixed upon a shaft 177. The

shaft is driven step by step in one direction by driving mechanism which is adapted to yield for the'purpose of avoiding breakage 5 of parts in case a hook becomes stuck. The

When the bell.

motive power for thefeedingdisk 176, is

taken from a pulley 178 aflixed to the main driving pulley 135. A belt 179 passing over the pulley 178 drives a pulley 180 on a stud 181. Rotation of the pulley 180 is transmitted by a pulley 182, belt 183 and pulley 184.- to a crank shaft 185. A disconnectible clutch is provided for connecting the pulleys 180 and 182 so that the feeding disk 176 maybe dlsconnected without stopping the rotatlon of the main pulley 135. For this purpose the pulley 180 is loosely mounted upon the stud 181 and is held thereon by a collar 186 pinned to the stud. A sleeve 187 loosely mounted on the stud 181 carries a pm 188 which extends through the pulley 182 and is adapted to be inserted in and withdrawn from a socket 189 in the hub of her 192 is formed with a spindle which 00-.

cupies the socket and is adapted to have telescopic movement therein. The -two members of the connecting rod are normally drawn together by springs 194.

The lever 191 is mounted upon a fulcrum stud 195, and its free end is connected by a- .link 196 with a vertically movable slide 197.

The slide is in 'turn connected by a link 198 with an oscillatory pawl carrier 199 loosely mounted upon the shaft 177. A pawl 200 pivotally mounted on the carrier 199 is adapted to coiiperate with a ratchet 201 affixed to the shaft 177 A spring 202 mounted upon the carrier 199 engages the pawl and 1s adapted to normally hold it against the ratchet.
